Specific embodiment
Referring to Fig. 1, it illustrates a kind of embodiments of vehicle hanging swing arm.The vehicle hanging swing arm 100 includes swing arm base
Portion 110 and the swing arm interconnecting piece 120 for extending protrusion from swing arm base portion 110.Wherein, swing arm interconnecting piece 120 is for connecting other vehicles
Suspension hardware, and air spring mounting portion 111 is set on swing arm base portion 110.Specifically, the air spring mounting portion 111
With first end face 111a, and extend the second end face 111b protruded, second end face 111b tool relative to first end face 111a
There is the surface accuracy higher than first end face 111a.The vehicle hanging swing arm 100 by formed stair-stepping first end face 111a with
Second end face 111b, and higher surface processing accuracy is provided in second end face 111b outstanding, avoid the surface of casting not
Smooth problem cooperates precision so as to improve with the installation of air spring.
As a specific example, first end face 111a can be set to casting plane, and second end face 111b is arranged
To be machined plane, for example, it can be realized by milling cutter machining.Second end face 111b, which has, as a result, is higher than the
The surface accuracy of one end face 111a.
In addition, mudhole 111c can also be arranged on the first end face 111a of air spring mounting portion 111, due to first end
Face 111a is lower than second end face 111b in height, therefore silt sewage encountered in use process converges to the first end face
It at 111a, and is then discharged rapidly via mudhole 111c, guarantees the clean and tidy of air spring working environment, and then improve it
Endurance life.More specifically, the extreme lower position on first end face 111a vertically can be set in mudhole 111c, thus
So that it is in the extreme lower position of entire air spring mounting portion 111 vertically, so as to most arrange fastly and as much as possible
The sundries such as silt sewage out improve the reliability of air spring.
At the same time it can also which sand losing opening 112 is arranged on swing arm base portion 110.112 one side of sand losing opening is used for outstanding in vehicle
It hangs in the casting process of swing arm 100 and passing away is provided, sand losing opening 112 and mudhole 111c on the other hand can also be made via pendulum
The inside of arm base portion 110 is connected to, so that the sundries such as the silt sewage that flows into from mudhole 111c can be discharged via sand losing opening 112
To the external world.
Optionally, swing arm base portion 110 and swing arm interconnecting piece 120 are the hollow member of casting and forming, so that each hole
Hole can be connected to inside swing arm, realize filth-discharging effect.
As an example, vehicle hanging swing arm 100 shown in Fig. 1 is configured to " H " type；Wherein, swing arm base portion 110
It is configured to extend transversely, and multiple swing arm interconnecting pieces 120 are configured to extend longitudinally at the both ends of swing arm base portion 110.
Above repeatedly refer to the directions words such as vertical, transverse direction and longitudinal direction.It is appreciated that the various it is mentioned herein this
The word of class direction is mounted on the orientation in carriage frame with component to be oriented.For example, vertically meaning in carriage frame
The direction at the top of vehicle frame is directed toward from bottom of frame；Laterally mean to be directed toward the direction on the right side of vehicle frame on the left of vehicle frame；And longitudinal direction is then anticipated
Refer to the direction being directed toward on front side of vehicle frame on rear side of vehicle frame.
Referring to fig. 2, a kind of embodiment of air spring is also shown herein.Peace is arranged in the first end of the air spring 200
Rib 210 is filled, and it passes through the second end on the air spring mounting portion 111 in installation rib 210 and aforementioned any embodiment
Face 111b cooperation.The high-precision surface of second end face 111b fit closely the two can, firmly install.
As an example, the installation rib 210 of the first end of air spring shown in Figure 2 includes being disposed radially
First rib 211 and the second circumferentially arranged rib 212.The two is intertwined to form radiation reticulated structure, thus real
The now cooperation with the second end face 111b on air spring mounting portion 111 more closely.
With continued reference to Fig. 3 and Fig. 4, it illustrates a kind of embodiments of vehicle suspension system.The vehicle suspension system includes
The air spring 200 addressed in the vehicle hanging swing arm 100 and aforementioned any embodiment addressed in aforementioned any embodiment,
It is completed under state, realizes fitting closely for the two.
In addition, although it is not shown in the diagrams, providing herein a kind of with the vehicle hanging system addressed in aforementioned any embodiment
The vehicle of system, therefore it also has corresponding technical effect.
Example above example and unrestrictedly illustrate vehicle hanging swing arm, vehicle suspension system and the vehicle of the application.
